Forecast Discussion – A warming and drying trend is expected this weekend. Friday through Monday we should expect mostly sunny skies, warm days and cool nights. Air quality should be in the AQI-Good category for much of Friday, Saturday, Sunday and Monday. The cool nights may allow PM2.5 (fine particulate) levels to build, and air quality could become AQI-Moderate at times. The daytime winds should help disperse the PM2.5 pollution. /MC (Issued 4/17/26 8:00AM)
